Abstract

Background: Composite resin is a material used as a restoration treatment that is the same color as teeth. Color changes in composite resin can be reduced by adding edible coating. Edible coating can be made from polysaccharides, proteins, and lipids. Objective: To determine the effect of chitosan coating on nanohybrid composite resin in coffee immersion on color changes. Method: Laboratory experimental research, with a posttest only control group design. The study consisted of 3 groups, namely 5 negative controls, 5 positive controls, 5 treatment controls that were given a 1% chitosan coating with immersion for 5 minutes. Each positive control group, negative control group and treatment group were soaked in coffee solution for 7 days. Results: In the negative control it was 15.3080 mV, the positive control was 23.0980 mV, the treatment group was 28.4960 mV. Conclusion: There is a significant difference in color changes between nanohybrid composite resin coated with chitosan and uncoated, indicating that chitosan has the potential as a coating material against dyes from coffee.

Abstract

The use of Generative Artificial Intelligence (GenAI) provides opportunities for MSMEs to improve content creativity, branding, and digital marketing. However, limited digital literacy and skills remain major challenges. This community engagement program aimed to improve the ability of MSME actors in Boja District to utilize GenAI for marketing activities. The program employed needs identification, training, hands-on practice, and mentoring. Participants were trained to use GenAI to develop prompts, promotional captions, content ideas, taglines, and content plans. The results indicated improved participants’ knowledge and skills in utilizing GenAI for content development, branding, and digital marketing. The program also encouraged the emergence of potential local digital champions who can share knowledge with other MSME actors. Therefore, integrating GenAI literacy, content development, branding, and digital marketing through practical training and mentoring can serve as an effective empowerment strategy for MSMEs in the digital transformation era.
